We'll miss Rebecca Romijn, but we actually think this is a good casting choice!

Actress Amber Heard is reportedly in talks to join the cast of X-Men: First Class as the seksi, smurfette-like shapeshifter Mystique!

So far, James McAvoy is the only actor confirmed for the Matthew Vaughn directed prequel - he'll be playing a young Professor X, but there are also rumblings that Rosamund Pike is up for either the role of Moira MacTaggert or Emma Frost!

Sounds like pretty solid additions! We're curious to see who else is going to officially sign up!

What do U think?? Who do U want to see join the ranks of mutant teens??
